Data 1;   Data 2




FAME Model output from a single time step of a ~50 year model run. Each panel represents a single species oxygen isotope values.

Predicted depth habitats from oxygen isotope values (Pracht et al., 2019).

Single shell oxygen isotope data down core for different size fractions (Metcalfe et al., 2015).

The impact of the pH with time, of the solution of deep-sea sediment and chemical pretreatment (Feldmeijer et al., 2013).
